1. A concentrator comprising:
a casing;
a separation membrane configured to section an inner space of the casing to form a flow path in the casing;
a first supplier configured to supply a first liquid from a first position of the casing to the flow path such that the first liquid flows along the separation membrane in a first direction;
a second supplier configured to supply a second liquid from a second position of the casing to the flow path such that the second liquid flows along the separation membrane in a second direction opposite to the first direction; and
a third supplier configured to supply a third liquid including a target component having a size that does not allow permeation of the target component through the separation membrane from a third position of the casing to the flow path, wherein
the third position is located between the first position and the second position in the first direction.
